0.2.2

This is a very quick follow up to 0.2.1, coming under 24 hours later with a huge bug fix that has been troubling me for a long time and I finally managed to splat it. Happy days! I also tweaked the undo / redo features slightly.

Update includes:

• Fix for mangled copy / paste text and general input bug
• Way more efficient input process
• Tweak the undo / redo feature to not make the file dirty unless it actually changes something.
